Expand description
A string or array of strings indicating the name of custom styles to apply to the mark. A
style is a named collection of mark property defaults defined within the style
configuration. If style is
an array, later styles will override earlier styles. Any mark
properties explicitly
defined within the encoding
will override a style default.
Default value: The mark’s name. For example, a bar mark will have style "bar"
by
default.
Note: Any specified style will augment the default style. For example, a bar mark
with "style": "foo"
will receive from config.style.bar
and config.style.foo
(the
specified style "foo"
has higher precedence).
A mark style property to apply to the title text mark.
